rozwiąż równaniaa)2(x+2)-3(x-1)+8 =3x-1b)x-1/2x-32xc) 1/3-(4+1/2x) -2
a) 2(x+2)-3(x-1)+8 =3x-1
2x + 4 - 3x + 3 + 8 = 3x -1
-x + 15 = 3x - 1
-x - 3x = -1 - 15
- 4x = -16 / : (-4)
x = 4
b )x-1/2x-32x = -31 x
c) 1/3-(4+1/2x) -2
- 4 - x - 2 = - 5 - x
a)2(x+2)-3(x-1)+8 =3x-1
2x+4-3x+3+8=3x-1
2x-3x-3x=-1-8-3-4
-4x=-16/:(-4)
x=4
b)x-1/2x-32x
x-1/2x-32x=-31,5x
⅓-4-½x-2=-5⅔-½x
Jeśli o to chodziło to na 100% jest dobrze :D Proszę o najj...
